what is a Sync Error on the pendant?

Pete et al,,what do you do when you get a Sync Error on the pendant? re-do electrodes? thanks-- Margoshes, Ph.D.New York State Licensed Psychologist

In the status bar (black bar across the top of the screen) there are three signal quality indicators:CH1, CH2 and Sync Errors.CH1 should be green when you are training it.  If not, in indicates there is probably a bad connection or electrode in that channel.  Re-prep and replace the electrode(s)--active and reference--until you get a green. CH1.

If you are doing 2 channels, then both CH1 and CH2 should be green.  (Obviously if you don't have electrodes in channel 2 it's no problem if it is showing red).Sync error relates to communication between the Pendant and its dongle.  BE expects 256 bits of data each second to be coming through the dongle.  When something less than that comes, BE warns you that something is interfering with the synchronization of the communication.

Most commonly this is the trainer or the client.  The Pendant and dongle should be able to " see " each other directly.  When you lean between them or put an arm between them to point something out on the screen, it's not uncommon for that to interfere and cause sync error to blink on.  If you place the Pendant on the client's shirt collar or shoulder on the same side of him/her that the dongle is on--and maybe you sit on the other side--that should minimize these errors.  If you place the pendant behind the client, blocked by the body, or with the desk, etc. interfering with its line of sight, there's greater chance of sync errors.

When sync errors get serious enough to last for several seconds, even slowing down or stopping the display in BE, something else is probably wrong.  Most common in my experience (but remember I often do workshops with 6 or 7 pendants in the same room running at the same time) is another Pendant/dongle combination.  Could be you forgot to turn off the HEG Pendant when you turned on the EEG.  Both will try to link up with the dongle and cause sync errors.  With multiple pendants in a training area, you can reset them to different channels.  This can also be the solution in the rare case that some other device is trying to communicate on the same RF channel the Pendant and dongle are using. 

I've heard a story of a 9-year-old boy who opened his neighbor's garage door every time he got his beta above threshold, though I frankly doubt it.  In any case, if it hadn't been so motivating, the trainer could have resolved it by changing the channel used by the Pendant/dongle.

If you go to Pocket-neurobics.com, find the Manuals link and you can download the Pendant AAA battery manual.  It's relatively short and easy to read and explains all this stuff and how to do it.Pete

thanks, Pete. I now see upon review that my whole session was 60-cycle garbage. No other pendants were on. I will check to see that pendant and dongle are communicating next time, and also make sure to go to Instruments 1 to check my signal before letting the client enjoy the video on Instruments 2.
